Timeshare, being a special tourism product, has achieved a remarkable growth and geographical expansion over the last decades, becoming a successful business choice for a great number of tourism enterprises globally. However, the scientific and theoretical approach of the product’s operational implementation has been delayed, whereas it has been limited mainly to following the developments in the market, unable to support businesses, entrepreneurial bodies and national and international tourism planning authorities. The cause for this is the absence of a commonly accepted theoretical foundation, which shall define the product within the framework of the tourism market and the other tourism products and which shall allow the examination, under a commonly accepted view, of the international operational implementation of Timeshare, the way it is produced and sold, as well as of the different Standards–Forms and their particularities. This paper aims at presenting the methodology for shaping the Standards–Characteristics Matrix of Timeshare and explaining its utility. The Standards–Characteristics Matrix is an international first attempt at codification, combined presentation and theoretical definition of the operational implementation of Timeshare, more specifically of its basic Implementation Standards and their Characteristics. The Matrix, as a product of study of the international bibliography and of the practical application of Timeshare in the market, is thus capable of assisting both official authorities and enterprises in their policy-making, strategic planning and decision-making, which shall aim at a correct interpretation of the past and a more efficient operational implementation of the product in the future.
